AVING
It is daily or weekly configurable function with “hour time
table” (if RTC on board) or depending from external digital
input. During the Energy Saving cycle the real setpoint is
calculated with the parameters ES10 and ES12:
SET+ES10
for chiller,
SET+ES12
for Heat Pump.
The differential for the function cut-in/out is depending by
ES11
for Chiller and
ES13
for Heat Pump.
20.1
Daily Programming
The daily programming is based on 7 parameters
ES03-
>ES09
corresponding to the 7 days of the week; the value
1 enable the function for that day.
Eg:
ES03 = 1
means that the Energy Saving is activated for
the whole 24 hours on Monday. If needed, repeat the
operation for the whole week ES04(Tue)..ES09(Sun).
20.2
Hour Time Table (with RTC)
Based on two parameters: ES01 Energy Saving start hour
and
ES02
Energy Saving stop hour.
Eg:
ES01 = 8.0
and
ES02 = 10.0
it means that the Energy
Saving is active from 8 to 10.0 for all the days of the week.
Eg:
ES01 = 23.0
and
ES02 = 8.0
it means that the Energy
Saving is active from 23.0 to 8.0 of the next morning; for all
the days of the week. This function is disabled if the
parameters ES01 / ES02 are both 0.
20.3
Energy Saving with External Contact
The function is enabled when the digital input, configured
as Energy Saving, is activated by remote contact.
